Some other options here:
You could also configure with:
./configure --with-rsh="/usr/bin/ssh -x" FC=ifort F77=ifort
Instead of using the '--with-rsh' configure option, you could just
export the environment variable LAMRSH in your .bashrc file:
export LAMRSH=ssh -x

I wonder why it is trying to execute:
/home/mahmoud/lam-7.0.6/share/ssi/boot/rsh/ssh
What does the following command return:
$ which ssh
It should return something like:
/usr/bin/ssh
Have you tried following the suggestions from the lamboot error message?
Something like:
$ /home/mahmoud/lam-7.0.6/share/ssi/boot/rsh/ssh -x
condmat10.ctpm.aeoi.org -n echo $SHELL
or better yet
$ /usr/bin/ssh -x condmat10.ctpm.aeoi.org -n echo $SHELL
